Man's greatest enemy in the world is his ego, the thought of self. This is the germ From which springs all evil in man. Even the virtues of the egoist turn into sin, and his small sins into great crimes. All religions and philosophies teach man to crush it, and there is nothing that can crush it better than love. The growth of love is the decay of the ego. Love in its perfection entirely frees the lover from all selfishness, for love may be called in other words annihilation.
